5.2 Detailed list of parameters
Function
Set a direct current exciting voltage level during the magnetic pole detection.
If [AL. 32 Overcurrent], [AL. 50 Overload 1], or [AL. 51 Overload 2] occurs during the magnetic pole detection,
decrease the setting value.
If [AL. 27 Initial magnetic pole detection error] occurs during the magnetic pole detection, increase the setting
value.
Setting range: 0 to 100
Response selection
The digit will be enabled when "Minute position detection method" is selected in [Pr. PL08].
Set a response of the minute position detection method.
When reducing a travel distance at the magnetic pole detection, increase the setting value.
For settings, refer to the following tables (Response of minute position detection method at magnetic pole
detection) for the setting value.
Load to motor mass ratio/load to motor inertia ratio selection
The digit will be enabled when "Minute position detection method" is selected in [Pr. PL08].
Select a load to mass of the linear servo motor primary-side ratio or load to mass of the direct drive motor
inertia ratio used at the minute position detection method. Set a closest value to the actual load.
For settings, refer to the load to following tables (Load to motor mass ratio/load to motor inertia ratio) for the
setting value.

Set an identification signal amplitude used in the minute position detection method.
This parameter is enabled only when the magnetic pole detection is the minute position detection method.
However, when "0" is set, the amplitude will be 100%.
